What happens if WordPress site URL is misconfigured?

In WordPress, the site URL is set in the configuration. What is the most likely visible effect if this URL is set incorrectly?

A The site redirects to a wrong or non-existent address causing a loading error

B The site loads normally but admin login fails

C The site loads but images and stylesheets fail to load

D The site shows a database connection error

💡 Hint

Think about what happens when the main address WordPress uses is wrong.

If the site URL is wrong, WordPress tries to load pages from that incorrect address. This causes browsers to redirect to a wrong place, often leading to loading errors or 'site not found' messages.

What is the effect of incorrect database credentials in wp-config.php?

If the database username or password in wp-config.php is wrong, what will WordPress display when trying to load the site?

A A blank white page with no message

B A message saying 'Error establishing a database connection'

C The homepage loads but no posts appear

D The login page loads but login fails

💡 Hint

Think about what WordPress needs to get content from the database.

WordPress needs correct database credentials to connect and fetch content. If credentials are wrong, it cannot connect and shows a clear error message about database connection failure.

📝 Syntax

Identify the syntax error in wp-config.php snippet

Which option contains a syntax error that will cause WordPress to fail loading wp-config.php?

Wordpress

<?php
define('DB_NAME', 'mydatabase');
define('DB_USER', 'user');
define('DB_PASSWORD', 'pass')
define('DB_HOST', 'localhost');
?>

A Using single quotes instead of double quotes in define

B Missing quotes around DB_HOST value

C Missing semicolon after DB_PASSWORD definition

D Missing PHP opening tag

💡 Hint

Check each line for proper statement endings.

In PHP, each statement must end with a semicolon. The line defining DB_PASSWORD is missing a semicolon, causing a syntax error.

Why does WordPress show a 'Too many redirects' error after changing site URL?

After changing the WordPress site URL in the settings, the browser shows a 'Too many redirects' error. What is the most likely cause?

A The theme is incompatible with the new URL

B The database is corrupted and cannot save the new URL

C The wp-config.php file is missing

D The new URL is set to HTTP but the server forces HTTPS causing redirect loops

💡 Hint

Think about how HTTP and HTTPS redirects can cause loops.

If WordPress URL is HTTP but the server redirects all requests to HTTPS, the browser keeps bouncing between HTTP and HTTPS causing a redirect loop.
